---------------------------------
{quote} I think test code rewrite is not so important now. I think first I have to remove
the rest of the deprecations and fix the test bug (see java-dev mail).
I ran the compilation with unchecked warnings turned on, only 38 warnings for core. I think
the rest in core should be doable now JUHU!

Ok - Makes sense. It would be nice to get it down to 0 soon..

> For my needs I've updated Lucene so that it uses Java 5 constructs. I know Java 5 migration
had been planned for 2.1 someday in the past, but don't know when it is planned now. This
patch against the trunk includes :
> - most obvious generics usage (there are tons of usages of sets, ... Those which are
commonly used have been generified)
> - PriorityQueue generification
> - replacement of indexed for loops with for each constructs
> - removal of unnececessary unboxing
> The code is to my opinion much more readable with those features (you actually *know*
what is stored in collections reading the code, without the need to lookup for field definitions
everytime) and it simplifies many algorithms.
> Note that this patch also includes an interface for the Query class. This has been done
for my company's needs for building custom Query classes which add some behaviour to the base
Lucene queries. It prevents multiple unnnecessary casts. I know this introduction is not wanted
by the team, but it really makes our developments easier to maintain. If you don't want to
use this, replace all /Queriable/ calls with standard /Query/.
